all 6 b/o hens look very pale

we've had extremely hot weather very quickly for the last two days. my hens have fresh food and water available all the time but last night and today - they are looking very pale in their combs and faces, is this normal? they are panting with wings down. they have plenty of access to shade - they free range on their own 1/4 acre.

I noticed the same with my girls today. It was exceptionally hot out this afternoon. I'm not really sure what else to say beside keep doing what you're doing with access to fresh water and shade! I remember seeing some threads about fans and other homemade cooling contraptions last summer. Maybe try doing some searches and see what you can come up with.

It is hot here too in NJ today. 90 degrees. Feels like July. I keep a few 2 liter pop bottles in the freezer with water in them. I put them in the coop today to help cool it. I also gave them fresh cool water 4x today. Plus, some cold fruit and veggies. Mostly they hung out under the coop where it was shady.
